The very rare specimen stock certificate is from the Chicago National League Ball Club, which is better known as the Chicago Cubs. The Chicago Cubs, one of the oldest Baseball Clubs in the U.S., is a founding member of the National League in 1876. Amazing piece of baseball memorabilia!

We believe this specimen certificate was printed in the late 1970s during the Wrigley's ownership years and was subsquently sold to the Chicago Tribune.

Specimen’s can be identified by their “specimen” stamp, stamped holes spelling “specimen”, or they are often issued with a serial number of a series of zeros. Often, they are also issued with no serial number at all. Specimens can also represent a design that was never issued. All of these attributes make the specimen stock certificate rarer than the issued version of the share. Many enthusiasts collect specimens as a whole new category of Scripophily.
